the node continues to count the errors during a given accumulation period. If 0 is entered as the threshold
value, the performance monitoring parameter is disabled.

Thresholds tab
Change the threshold if the default value does not satisfy your error monitoring needs. For example,
customers with a critical STS-1 installed for 911 calls must guarantee the best quality of service on the
line; therefore, they lower all thresholds so that the slightest error raises a TCA.
12.2 Intermediate-Path Performance Monitoring
Intermediate-path performance monitoring (IPPM) allows a nonterminating node to transparently
monitor a constituent channel of an incoming transmission signal. ONS 15600 networks only use line
terminating equipment (LTE), not path terminating equipment (PTE).
